What would I > know? I have a genset for the house, but I live in Southern California with our propensity for earthquakes. It's not only good for those, but for brush fires as well. While I wasn't affected during the fires (other than dealing with a lot of smoke, soot and ash), a friend (whom I convinced to get a small genset) was. His was the only house with power since the high-tension lines were fried by the fire and it ended up being used as a command, coordination, staging and rest area for police and fire people. He's a HAM, so his radios could also be used. His refrigerators and freezers kept going, so he was also able to keep donated food cold and cook for the emergency workers. I think he said he and his wife fed about 300 of them over two days. Turned out rather well for all. Oh, his genset runs off LP gas in an underground tank. ---------------------------------------------------------------------- - Rick Stevens, Principal Engineer rstevens@xxxxxxxxxxxx - - CDN Systems, Internap, Inc. http://www.internap.com - - - - If at first you don't succeed, quit.
